RE: nat problem [7:55537]
Hi, Looking at this, there appears to be no dynamic routing happening. The gateway of last resort is on a different network than E0/0 and E0/1. Can you actually reach 10.1.255.254 by any other means ?

Re: nat problem [7:55537]
Two comments I would like to make. 1. Richard, the gateway of last resort IS on the same network as E0/0. The subnet mask is 255.255.0.0. 2. The route you added tells the router that 1.1.1.1 is out interface E0/0. It's on E0/1. So that definitely won't work. If you remove the NAT statements, are you able to ping everything on both sides? If not, then you have a routing issue. If so, then it is something else. Is there something missing from this config, like access-lists, etc. that may be causing the problems? If you are just wanting to NAT the one IP address, the first ip NAT line and the associated access-list are unnecessary. Try removing them from the config and see what happens. bbfaye wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... hi eb, I met a problem here: a Cicsco 2611#: Router#show running-config Building configuration...

sorry Robert,I did add the route of 1.1.1.1 on interface e0/1 at 14 Oct 2002 14:08:08 - , [EMAIL PROTECTED] (Robert Edmonds) wrote: -- Two comments I would like to make. 1.
